Here's some before and afters where I had to use Super Degreaser at 4:1 to get this tire dressing off. I tried full-strength Simple Green, APC+ 10:1 and 4:1, Dawn, and a mixture of all three to no avail. The Super Degreaser also cleaned out the brush that I was using as well that got all gunked up while trying to scrub the tire with all of the other products. The dressing that was on these tires was Black Magic Platinum Tire Gel.

I also used some on the wheel to try and get whatever it is on there off. It did take some off as you can see (it lightened the stain), though I never tried more than that one application.

Before (even after scrubbing and scrubbing with all of the above)





After (Super Degreaser 4:1)
